,To all ir/iom it muy concern.'

ylle it known. *hat I, llxnnow l). Snvxsn, a resident ot' ,i-shland, `inthe county of Boyd and.. State of Kentucky, have invented a new anduseful ln'iproveinent in BalileYalls for v Jiiocoinotire FireBoxes. oiwhich the folvided with the low'ingis a specilication.

This invention relates to battle walls .for floedinotire tire boxes. yflThe object oi the invention is to improve the arrungenicnt of firebrick forming such baille walls, in order to reduce the weight end costot' the .Vire brick, and particularly to .furnish a new and improvedforni of side brick ot' simple construction, which are so shaped as tobe easilvY secured in the fire box, which are reversible and can be usedon either side the fire box, and which also cnn be used in. lire boxeswhere the side walls converge toward each other. I

ln the accompanying drawing Figure l represents a longitudinal sectionthrough a .tire box provided with my improved battle wall, the sectionbeing tn k'en on the line l-l.

Fig. iig. 2 is :i transverse section on the line Qh, Fig. l Fig. 3 is aplan View of the baille wall; Figf is et perspective View ot the underside of one of the side bricks.

v.ln the drawings l represents the vfront well of the locomotiveire box.which is prousual firing opening Q 3 represents the resr wall ofseidtire box; 4: the top thereof; and 5 the grate. Extending between thefront and renr side walls are the usual long ndinal tubes (3 forsupporting the liiiie wall. The fire box. as shown, is provided withtour such longitudii'ial tubes il which are connected in the circulationsini-- teni of the boiler, and extend substcntiallnv parnllel to thecentrnl longitudinal axis ot tbe .ire box. at least tor 'those portionso't th'b l 'ctn wlucl support the baille w all. rlhe le walls i oi' thefire box may be parallel 'to each other. but insoine ceses may con,-

'to-wit. three central rows S, and two side rows .fh-which takentogether storni a sort of inverted arch extending troni side to side'o'fthe tire box. The brick l0 ot' the three intermediate'rows have theirlower corners cut out-, as at ll, to forni refy cessed lfaces restingupon the four cinculnl. tubes 6, and,`a'lso haveV zipartgoi thefv towardthe rear wall of the tire box,r

The brick llof the side rows are inclined between the side walls 7 volthe re boxsnd the outer circulation' tubes. .Y cisl shape. being formedsubstnntially'of flat plates of. the saine thicinies` throughout.' andare curved or arched atf'thei r outer edges in two directions. first ina horizontziil plane, as indicated at 15'. find second in :i verticalplane, es indicated at 16. rhis takes care o: any inequalities in theside walls ot' the lire box, and insures that the side brick will het' afirm bearing' against the side walls, even if the latter converge towardeach other.. and also a lirni tion tubes. The under side of cach sidebrick le is provided with one or s. plurality of downwardly extending'lugs or projections 17,'two being shown. These lugs or projections aremolded integral with. the brick and are shaped to forni curved bearingsurfaces 1S, which abut against the outer circulation tubes 6 andprevent the brick from dropping down between said tubes and the walls ofthe lire box. The lower inner horizontal edges of the bricks lfl'areslightly out away. `r beveled, ns at 19. to torni longbearing surfacesextending' the full length ot' the brick, and resting directl)Y upon thecirculation tubes 6. rlhe side brick consequently have in eii'ect avthree-pointsuspension. that is. they bear upon the4 tubes forsubstantially their entire length or at both ends and Contact with theside wells ot' the re boxv at it single point. This prevents liabilityot the brick tilting' in use or troni becoming vin any inanner displacedtroni. the circulation tubes. The upper inner edges ot' the brick :irealso sloped back or beveled slightly. as et 20, to prevent tliein lromfusing with the adjaunder extreme high The side brick llt are' also tenipeintures.

When the side Walls of the lire box converge,different side brick longitudinally of the lire box will be of differentWidths, to take care of the -varying distance between the side Walls andthe -outer circulation tubes at different points longitudinally in theire box. Preferably, the different brick Will be of such size that theinclination of all brick will be the saine. However, if desired,diffiring opening and can be placed nponthevv i set `my hand.

The inclination of theside brick is such that its Weight tends to make it'set- They are allmade of such size as to be easily inserted through the tle more firmly'in lace and to Wedgein between the side Wa ls and the outer cir-cnlationtubes.
